Polygon

Dream big with All Ultrex Polygon windows. Rectangles, triangles, pentagons and more-8 unique shapes in all-give you the freedom to create almost any window arrangement you desire. And thanks to the strength and precision of Ultrex pultruded fiberglass, Integrity Polygon windows can be as large as 49 square feet with a maximum span of up to 9 feet.

Round Top

All Ultrex Series Round Tops are the one curved-edge window whose strength matches its beauty. Made from glass-reinforced composite and finished with Integrity’s acrylic capping technology, you get a stunning complement to any Integrity All Ultrex Series window that will last for years.

Glider

Glider windows are the perfect alternative to Casement windows where a swinging sash is not practical. Each Integrity Glider window is manufactured specifically for horizontal operation, unlike other gliders that are essentially Double Hung windows turned on their sides. The strong Ultrex fiberglass interior and exterior ensures the window glides smoothly and stays true on even our largest Glider windows.

Casement / Awning

The low-resistance crank make this an ideal window for almost any room that needs a little fresh air.

Single Hung

The performance of maintenance-free Ultrex fiberglass is now available in this affordable Single Hung window. Traditional styling and sleek sightlines match the appearance of Integrity Polygon windows to create beautiful assemblies when paired together.

Double Hung

This classic window style gets a contemporary twist with an Ultrex fiberglass exterior and interior delivering high style and a durable finish from every angle. Double Hung windows are ideal for second floor bedrooms or as part of a beautiful bay window combination. Both the top and bottom sashes tilt inward for easy cleaning.
